SOAP-DISPENSER.

Specification of Letters Patent.V Patented Jliizbj-I'Biz Applicationiled Septemberl, 1908. Serial No. 451,167.

To all whom it '1mg concern:

Be it known that I, OHAnLns WADE, a citizen 'of the United States,residing at -East Orange, in the county of Essex and to improve andsimplify apparatus of this class, and attain the discharge of the soapyliquid in as convenient and positive a manner as possible. V

In carrying out the invention I provide means by which the soapy liquid1s positively acted upon in its ejectment from the reservoir, not.depending on gravity for its impelling force atanywstawithe-operation.I 'considerthis an limportant characteristic of the invention, 'as theliquid is sometimes thick and viscousan'ddoes not run freely throughnarrow passages where there is no other impelling force than the slightpressure due to the weight of the small fluid column available I makeuse of a. form of pump mechanismhaving valves,

and I further provide a form of automatic sign'1 designates a receptacleor vessel conor check valve for controlling the` inlet opening ofthereservoir. I haveillustrated specially constructed valves -havingspecialadvantages, 'as will 'be later more fully set forth.

Having these various and other objects in view, Imy inventionconsists'in-thcieatures of construction and combination as herein. ,after setfforthand claimed.

In the drawings: Figure 1 is a side elevation I embb ying theprinciples7 of myinvention; Fig. 2 isa detail sectional view of thevalve which controls the 'inlet or feed orifice, and

Fig. 3 is a similar viewjshowing a slightly modifiedconstruction.l

Referrin .to'the drawing in `:which like parts are eslgnatedby the samereference veniently made of glass-.and insetand ce.d

artly in section,'of a soap dispenser screws 4. Vtithin the base 2'iscontained a, pump mechanism for ejectmg the soa-py` liquid.

The rec'eptacle l has an opening 5 at its upper end in which' isreceived a small metallic or other cage-6 adapted to contain and guidethe inlet valve. I make the cage 6 with a flange or shoulder 7 adaptedto con-' tact with the interior surface of the recep tacle 1 around theopening 5. The upper ex# terior portion o'f the cage 6 is threaded toreceive a nut or collar 8 which can be f screwed down on the cage so asto coperate with the fiange 7 and firmly hold the cage 1n its place. Thecage 6 is of generally 'tlrimble shape, closed at its lower end 9 andhaving slots or openings 10 adjacent thereto' which establish a freecommunication to the interior of the receptacle l.

lLdesignates a. ball or other valve supported within the cage 6 andimpelled upward by a spring l2. I have sho'wn a cupshaped valve l1 and aform ofspring -12 having a reduced end 13 whichventers the interiorofthe cup 1l so as to retain the same in its central position'.

14 designates a cap having an interior threaded portion l5 adapted toscrew upon the upper threaded extremityof the cage 6 It is evident thatwhen the cap or coveu 1st 1sscre\ v e dinto place, the receptacle4T isgiven a imsned and ornamental outline, and

at the saine' time a convenient valveiseatjs rovided., l `fIhe soapyliquid maybe' supplied 'y pouringit into the valve o erung 16 from avessel having any suitable rschargespout, the valve 11 being depressedinto its cagel in this actionlV base chambered orrecessedftrans'ver'sely inward from its exposed side'withfia cylindpialbore L8 which constitutes the barrelpr cylinder oftthe pump.

rointhe pm p bore 18 into the receptacle j 19 designatesal passageextending upward 1, and through which the soapy liquid may enter thepump chamber.

20 designates a plunger made comparatively lonv in practice and having apistonrod 21 with a thumb-button 22 which can be depressed to 4impel theplunger 20 inward.

23 denotes a cap screwed upon a threaded extremity 24 of the base 2 andadapted to inelose packing material 25,if desired, thereby constitutinga gland for the piston rod. 'lhe plunger 20`is normally imp elled to itsouter position shown in Fig. 1 by a spring 26 contained within the boreof the pump chamber. .At its inner end the pump bore is narrowed toforni a chamber 27 for the valve `28. I make the valve 28 similar to thevalve 11, already described, in the form of a cupshaped, sheet metalpart impelled by a spring 29 having a reduced extremity 30 which entersthe.v cavity of the cup.

31 designates a perforated disk or washer constituting the valve seat'for the valve 28, being fixed within the pump bore or recess at asuitable point for this purpose.v This plate or washer is also adaptedto constitute an abutment for the spring 2G. 32 designates a dischar espout or nozzle having a passage 33 whic communicates with the interiorchamber'27 of the pump.

In use the receptacle l is lled with the soapy liquid or compoundthrough the opening 16, as already described. When it is desired toobtain a quantity of the soapy compound, the button 22 is depressed, freing the plunger 20 inward and compress ing the liquid in the space 26past the valve 28 and outward through the discharge nozzle 32. In thisaction the opening 19 1s closed by the plunger itself as soon as thelatter has moved through a sli ht range of its movement, so thatthereailcr the ejection of the soapy compound is accomplished withabsolute positiveness. When the plunger 20 starts to return, a partialvacuum is created i in the pump bore or chamber on account of theimmediate closure of the valve 28 by its impelling spring. Into thisvacuum the soapy compound is quickly forced by atmosplierie pressurethrough the opening 19 as soon as the latter is uncovered by themovement of the plunger. The pum chamber is thereby immediately filledwit a new supply of soapy .com ound Without de ending on gravity or oter factor of suc certain character or ma nitude.

In Fig. 3 I have il ustrated a slightl modified construction of inletvalve in whic thenut or collar 8 is dispensed with. -In this case thecap 14 screws directly upon the upper threaded end of the cage 6 andconstitutes the retaining means therefor in addition to its function asa valve seat. In other respects theconstruction of Fig. 3 is betweensaid similar to that @#Fi 2 and need not there fore be more pa'ti'cuarly described.

1. In a soap dispenser, a receptacle, a base for said receptacle'havinga pump bore and also a port leading from said receptacle to said bore, aplunger in said bore, means for normally forcing said plunger to itsoutermost position, a perforated disk having the perforation therein insubstantial alinement with the axis of said plunger, a check valvenormally closing said perforation, said base having a recess therein inwhich said valve is disposed, and a downwardly projecting nozzleopening'into said recess, said longer being movable toward said disk andthe arrangement of the above recited parts being such that the initialmovement of the plunger closes the port from said receptacle, the fluidin said bore being positively ejected by the continued advance of saidplunger through said disk and out of said nozzle, in close proximity tothe hand of the operator, the axial position of the check valvepreventing. frumming up of the same by the eiected Hind.
